Audit Add DB User Event Class
Applies to: 
SQL Server
Azure SQL Database
Azure SQL Managed Instance
The Audit Add DB User event class occurs whenever a login is added or removed as a database user to a database. This event class is used for the sp_grantdbaccess, sp_revokedbaccess, sp_adduser, and sp_dropuser stored procedures.
This event class may be removed in a future version of SQL Server. It is recommended that you use the Audit Database Principal Management event class instead.
Audit Add DB User Event Class Data Columns
| Data column name | Data type | Description | Column ID | Filterable |
